General Covariance in Quantum Gravity at a Lifshitz Point
Petr Horava, Charles M. Melby-Thompson
In the minimal formulation of gravity with Lifshitz-type anisotropic scaling, the gauge symmetries of the system are foliation-preserving diffeomorphisms of spacetime. Consequently…

Emergent Gravity at a Lifshitz Point from a Bose Liquid on the Lattice
Cenke Xu, Petr Horava
We propose a model with quantum bosons on the fcc lattice, which has a stable algebraic Bose liquid phase at low energy. We show that this phase is described by emergent quantum gr…
